Antisocial personality disorder (ASPD) is described by the American Psychiatric Association's Diagnostic and Statistical Manual, fourth edition (DSM-IV-TR), as an Axis II personality disorder characterized by "...a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood."

The World Health Organization's International Statistical Classification of Diseases and Related Health Problems', tenth edition (ICD-10), defines a conceptually similar disorder to antisocial personality disorder called (F60.2) Dissocial personality disorder.

The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders incorporated various concepts of psychopathy/sociopathy/antisocial personality in early versions but, starting with the DSM-III in 1980, used instead the term Antisocial Personality Disorder and focused on earlier behavior instead of using personality judgements. The World Health Organization's ICD incorporates a similar diagnosis of Dissocial Personality Disorder. Both the DSM and the ICD state that psychopathy (or sociopathy) are synonyms of their diagnosis.

Psychopathy and sociopathy are terms related to ASPD. ASPD replaced psychopathy as a diagnosis in the DSM but the terms are not identical. Psychopathy is now (like sociopathy) usually seen as a subset of ASPD.
